A signal processing circuit is disclosed for providing fuze-on-jam capability in a target detecting device, while in the presence of continuous wave or continuous wave noise jammer signals. A target detection system will protect the target detecting device from noise jammers and continuous wave radars or continuous wave jammers by providing a circuit which samples the negative or positive bias produced by the noise modulated CW signal and produces either positive or negative polarity as seen by the antenna. If negative pulses are produced, they will actu...
1. In a signal processing circuit for use in a passive target detecting device, the combination comprising: (a) signal receiving means for receiving signals from radiating targets for producing negative and positive output signals, (b) sampler circuit means coupled to said signal receiving means for periodically sampling said negative and positive signals for producing output negative and positive signals of a predetermined frequency, (c) mixer circuit means having a first input coupled to said signal receiving means and a second input coupled to sa...
